Debian 12: DSA-5783-1 Critical: firefox-esr code execution issue

Multiple security issues have been found in the Mozilla Firefox
web browser, which could potentially result in the execution
of arbitrary code.

Debian follows the extended support releases (ESR) of Firefox.
Starting with this update we're now following the 128.x releases.

Between 115.x and 128.x, Firefox has seen a number of feature
updates. For more information please refer to
https://www.firefox.com/en-US/firefox/128.0esr/releasenotes/?redirect_source=mozilla-org

For the stable distribution (bookworm), these problems have been fixed in
version 128.3.0esr-1~deb12u1.

We recommend that you upgrade your firefox-esr packages.

For the detailed security status of firefox-esr please refer to
its security tracker page at:
